IMPROVED sLEn-BRAKE.

' The Schedule referred to in these Letters Patent and making part o! the same.

To all whom 'it may concern Be it known that weJAMns B. STOREX and IsAAc N. Ross, of Butler, in the county of Butler, and State of Pennsylvania, have invented a Inew and useful mafchine, beingV a Self- Qp'erating` Lock or.. Brake for .Sleds and Sleighs; and we doherebyI declare that the following is a full, clear, and "exact description of the construction and operation of the same, reference being had to the annexed drawing, making a part of this specification, in which- No.` 1 represents a groove in ythe runner of' the sled or sleigh, said groove to be plated with iron, in which the ends of the roller will be inserted; when the runner of the sled is too narrow to admit of groove of proper length, then to be supplied by bolting on each side `an iron plate,on which sides and ends 'will project, and form a groove,`in which the ends of the roller will be'tinserted in like manner as in groove in runner.

No. 2 represents the roller, made in the same form and style of the ordinary roller, having iron bolts projecting from each end,whioh are inserted into grooves, No. 1.

N o. 3 represents thev main bar, running across the sled or sleigh, and entering a knee on each side, at which place the knees will be plated with iron.

No. 4 represents cranks or elbows, extending from main rod, N o. 3, in which blades are fastened.

No. 5 represents the blades, which hang fromV bolts, and are adjusted as to length bysaid bolts, by putting in upper or lower hole in blade.

No. 6 represents crank or elbow, in which the oonnecting-rod is fastened by bolt.

No. 7 represents joint where the connecting-rod is fastened to roller, allowing the tongue to rise and fall as the grade ofthe road frequires.

N o. 8 represents clips, in which the blades rise and fall; also hold blades to their proper p1aees,and prevent them from being forced back when cutting vinto snow orglce.

b No.9 represents connecting-rod from roller to main ar. l

The lock or brake is so constructed that you cannot ypull and lock at the same time. yWhen the sled or sleigh commences to run of its own accord, or without pulling, the rollen goes gradually back, which lowers the blades so they cut into the snow or ice. Again,

ywhen the team pulls, let it be ever so slight, it raises the blades, which, in itself', is a great safety to vehicles on runners, saving all shocks produced by catching on gravel, rocks, &c., with your brake or lock down.

Inshort, the lock or brake is under full control oi' the draught, locking only when necessary, and never when not necessary.

Again, our lock or brake is attached to the sled or sleigh, and not tolthe bed or box, making it a lockor brake that is always at its post, nodii'erence what you wish to haul, bed on or off'. l

What we claim as our invention, and desire to secure by Letters Patent, isp The adjustable dogs 5,.pivoted to the cranks or elbows 4 of the rock-shaft 3, which has also a centrecrank or elbow, to which is pivoted the connecting-rod 9, joined to the elbow 7, on the sliding roller 2, all constructed, combined, and arranged as herein shown and described.
